oiliness. The following notes taken may assist in the recog- 

 nition of this species : 



Palpi sordid white, rather stout, scarcely reaching to the lower 

 border of the insertion of the antennae, apex of second joint pale. 

 Head sordid white, with some sheen, smooth scaled, finely speckled 

 with pale fuscous. Basal joint of antennae sordid white, rather broad, 

 one-half longer than wide, pecten setaceous intermixed with some 

 scales, stalk grayish-fuscous, not excised above the base, simple, mod- 

 erately robust, neither ciliate nor pubescent. Thorax sordid white, and 

 like the head, speckled with pale fuscous, Forewings elongate — more 

 than in chalcofrontella , white, evidently dusted with fuscous, basal 

 part of costa dark purple-brown, at one-fifth, there is a transverse costal 

 spot reaching to the fold, but more distinct on the costa; apparently, 

 there is an outwardly convex, rather wide fascia at one-third, but 

 whether entire or not could not be determined, wider at the dorsal 

 margin and equidistant from the base at both margins, just before the 

 middle and nearer the costal margin is an elongate spot, two smaller 

 dots at end of cell ; cilia grayish, speckled with white and fuscous 

 scales, a dark line along the periapical margin but separated from it 

 by a pale line. Anal brush pale ochreous. Underside of body and 

 legs grayish- white, the latter suffused with fuscous; end of tibiae and 

 tarsal joints paler. Venation not determinable. 



The specimen bears Chambers' label, " Clemensella; Ken- 

 tucky, Chambers."

 of the costa, mixed with some ferruginous scales ; a similar patch 

 before the middle of the costa exhibiting more of the ferruginous color-

 tremity of an elongate-ovate blackish-brown discal spot, beyond 

 which, at the end of the cell, are two smaller spots of the same color, 

 which is also faintly reproduced in a diffused patch or cloud on the 

 dorsum beneath them and on the costa beyond them ; cilia hoary
